AHA (alpha-hydroxy acids) are one of the best and desired ingredients in the skin-care pantheon of greats. For very good reason – their very effective exfoliating and anti-aging benefits.
But (there’s almost always a but), AHA can be irritating to the skin. So one of the best ways to ease your skin into AHAs is with a facial cleanser. We round up our favourites for you.
What are AHAs and what do they do for your skin?
Alpha-hydroxy acids (AHA), aka fruit acids, are natural acids often found in foods like sugar cane (glycolic acid), citrus (citric acid), milk (lactic acid) and apples (malic acid). They:
- are water-soluble, so they only exfoliate the top layers of your skin.
- can also be manufactured synthetically.
- are chemical – as opposed to physical – exfoliators, which melt the glue that holds dead skin cells to the surface of your skin.
- are a good gentle alternative to physical scrub exfoliators as they don’t rub or tug the skin.
- are better if you have drier, more mature skin.
Removing dead skin build-up allows newer, fresher, healthier-looking skin to emerge, so skin looks more youthful and radiant. AND removing the old barrier allows moisturizers and ingredients to penetrate the skin better.
They are useful in the reduction of acne scars, hyperpigmentation and other discolorations.
Why are AHA cleansers good as opposed to a treatment/serum?
AHA cleansers usually contain AHA at low strengths, which allows your skin to build up tolerance because it has short contact time. The formulation may also include other active ingredients to either stimulate or calm the skin.
As your skin acclimates, you can experiment with leaving the cleanser on a bit longer as an exfoliating mask for a deeper treatment.
Pick your potion
Different AHA forms have different functions. The most popular are:
Glycolic Acid (derived from sugar cane), which is suitable for all skin types. It works to refine uneven skin texture by removing the dead cells from the surface of the skin without drying it out, while stimulating deeper collagen production.
It is extremely effective for treating fine lines, dullness, breakouts and uneven textures.
Lactic acid (found in milk, tomato juice and bilberry, for instance), has an intensely moisturising action on dry skin. It leaves skin brighter, smoother and softer. It helps with hyperpigmentation, dark spots, sun damaged skin, fine lines, and a dull complexion.
Polyhydroxy acids (like gluconolactone, galactosen and lactobionic acid) are the more gentle chemical exfoliant. They have larger molecules, so they don’t penetrate as deeply as AHAs when applied to the skin. This makes them less irritating and better for sensitive skin.
Introduce your skin to AHAs slowly. The exfoliating action can be a bit drying and irritating at first. So start using them every other day, choosing a product with a mild percentage and monitor how your skin reacts. Once your skin acclimates, you should be able to start using them every day.
Wear sun protection. Daily application of sunscreen and limiting sun exposure are essential, as using AHA-infused products regularly can increase your skin’s sensitivity to the sun, making it more prone to damage.
Avoid using it on open wounds.
If irritation persists, stop using it.
Can you use AHA cleansers daily?
It depends on the strength of the AHA as well as other ingredients. You should stick to concentrations between 4% and go up to 10% max.
You can use AHA cleansers on chest and back breakouts as well, a couple of times a week.
